Within a state or territory, the same name is often used in a number of different regional systems; however, the boundaries will usually differ.
For example, the government in Western Australia established 9 regions for economic development:
Gascoyne Goldfields-Esperance Great Southern Kimberley Mid West Peel Pilbara South West Wheatbelt
[Retain 2 words in South West, and do not insert a hyphen; however, the hyphen in Goldfields-Esperance can be replaced with an en dash.]
The Western Australian Department of Water has 8 regions for reporting about water, but only 3 of these (Kimberley, Pilbara and South West) are also used for economic development:
Goldfields Kimberley Kwinana Peel Mid West Gascoyne Pilbara South Coast South West Swan‑Avon
Also in Western Australia, there are 14 Bureau of Meteorology forecast areas, 26 IBRA regions (some crossing state borders) and 21 floristic regions. The Australian Bureau of Statistics defines 9 major statistical areas (SA4) in Western Australia. For electoral purposes, Western Australia has 15 federal electorates. At a state level, there are 6 regions for election to the upper house of parliament (Agricultural, East Metropolitan, Mining and Pastoral, North Metropolitan, South Metropolitan and South West) and 59 electorates for the lower house.
